Hello all, I have a quick question about the I2C bus on the Beaglebone Black.
I have built a system with a number of I2C slaves, but sometimes (rarely, once in 50,000 communications or less) they seem to hang and hold the bus in a fixed state. The I2C standard in theory has a fix for this (toggling the CLK 9 times <https://bits4device.wordpress.com/2017/07/28/i2c-bus-recovery/>), which forces the slave to release the bus. Is this fix implemented for the Beaglebone Black? I figured it might be only in recent Linux kernels, and hence I am upgrading my system to Debian 10/Linux 4.19 (previously it was the default Debian 8). However, I saw on a Raspberry Pi forum (here <https://www.raspberrypi.org/forums/viewtopic.php?t=231779>) that bus recovery functionality might be chip-specific, and so I worry that this may functionality may not exist for the AM335X. If not, how might I go about implementing it? Thank you in advance for any assistance. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
